Driving Make sure system is unplugged and properly stowed before driving the vehicle. While not in use, make sure the protective cover seals the prongs of the engine block heater cord plug. BRAKES Occasional brake noise is normal. If a metal-to-metal, continuous grinding or continuous squeal sound is present, the brake linings may be worn-out and should be inspected by an authorized dealer. If the vehicle has continuous vibration or shudder in the steering wheel while braking, the vehicle should be inspected by an authorized dealer. Refer to Brake system warning ! P light in the Instrument Cluster chapter for information on the brake BRAKE system warning light. Four-wheel anti-lock brake system (ABS) Your vehicle is equipped with an Anti-lock Braking System (ABS). This system helps you maintain steering control during emergency stops by keeping the brakes from locking. Noise from the ABS pump motor and brake pedal pulsation may be observed during ABS braking and the brake pedal may suddenly travel a little farther as soon as ABS braking is done and normal brake operation resumes. These are normal characteristics of the ABS and should be no reason for concern. Using ABS When hard braking is required, apply continuous force on the brake pedal; do not pump the brake pedal since this will reduce the effectiveness of the ABS and will increase your vehicle's stopping distance. The ABS will be activated immediately, allowing you to retain steering control during hard braking and on slippery surfaces. However, the ABS does not decrease stopping distance. ABS warning lamp The ABS lamp in the instrument cluster momentarily illuminates ABS when the ignition is turned on. If the light does not illuminate during start up, remains on or flashes, the ABS is disabled due to a malfunction and needs to be serviced. 226 2008 Sable (mgo) Owners Guide (post-2002-fmt) USA (fus)
